PROBLEM TO BE SOLVED: To provide a permanent magnet rotary electric machine reduced in torque ripples. SOLUTION: The rotary electric machine has a concentrated winding stator 2, having teeth 4 each having a protruded end surface in a rotor side and coils 5 wound around the teeth; and a rotor 3 having: an armature 12 defining a cylindrical surface; and a permanent magnet 14 provided with an internal surface forming one part of a cylinder that matches the shape of a cylindrical surface of the armature, and a flat external surface that faces a stator. Stator teeth each have an angular offset with respect to an axial end. COPYRIGHT: (C)2007,JPO&INPIT
